To all whom) it may concern:

Be it known that I, HERBERT B. GILLETTE, a citizen of the United States,residing at Benton Harbor, in the county of Berrien and State ofMichigan, have invented certain new and useful Improvements in Bearings;and I do hereby declare the following to be a f ull,clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to a new and useful improvement injournal-bearings, and is especially adapted for use in the wheel-hubs ofmill and freight-house trucks. Its object is to provide a device of thischaracter which will be simple and inexpensive of construction anddurable in use.

To these ends the invention consists in providing the hub with a box ofpeculiar construction adapted to receive the axle and a series ofrollers thereabout and means for retaining the rollers in properposition. An adjustable collar is provided upon the shaft, whereby theswing or sway of the wheel may be taken up or prevented.

The invention also consists in the further novel constructions andcombinations of parts hereinafterzmore fully described and claimed, andillustrated in the accompanying drawings, showing the preferred form ofmy invention, and in which-- Figure 1 is a side elevation of a wheelmounted upon an axle and embodying my improvements. Fig. 2 is a planview thereof; and Fig. 3 is a section on line 3 3, Fig. 2. Fig. 4 is asection on line 5 5, Fig. 2.

Referring to said figures by letters of reference, A is the axle, uponwhich is loosely mounted a collar B, provided with a set-screw 12,whereby it may be secured to the axle at any desired position thereon.The hub of the wheel, which may be of any preferred construction, isprovided with a box D, having a radial flange D upon one end. Betweenthe flange D and a hub-plate E, which surrounds the end of the outerwall of box D, are bolted the inner edges of the plates 0, of which thebody of the wheel is preferably made, as shown. The box D has aninwardly-extending flange d, which is to provide space between the axleA and the wall of the box D to receive the friction-rollers F, thediameter of which is such that when placed within said space theiropposite sides will bear against the box D and the axle A. The rollersare preferably provided with rounded ends, as shown. A ring G is fittedin a circular recess E, formed by the hub-plate E, and serves to retainthe rollers upon the axle A, between it and the flange d. This ring issecured to the box 1), preferably by means of screws 6, as shown. Thewheel may be secured to the axle in any desired manner, as by means of apin H. It will be obvious that by this construction I obtain a devicewhich is extremely simple and inexpensive of construction, but which is,nevertheless, strong and durable and which will overcome all end thrustof the rollers. Moreover, by providing the adjustable collar the wheelmay be readily tightened in position and all swaying or swinging thereofprevented.

In the foregoing description I have shown the preferred form of myinvention; but I do not limit myself thereto, as I am aware thatmodifications may be made therein without departing from the spirit orsacrificing the advantages thereof, and I therefore reserve the right tomake such changes as fairly fall within the scope of my invention.

Having thus fully described my invention, what I therefore claim as new,and desire to secure by Letters Patent thereon, is-- 1. The combination,in a wheel, of a box, outwardly and inwardly extending flanges at oneend thereof, a hub-plate surrounding the opposite end of the box, a ringsecured to the said box, and rollers confined between the box a box,outwardly and inwardly extending flanges at one end thereof, a hub-platesurrounding the opposite end of the box, a ring secured to said box, andfriction-rollers intermediate the box and the axle therein and I Intestimony whereof I aflix my signature in presence of two witnesses.

HERBERT B. GILLETTE.
